STOVEPIPE-CLAMP.

Specification of Letters Patent. Patented. M 17, 1921 Application filed April 26, 1920. Serial No. 376,716.

T 0 all whom it may concern Be it known that I, BASCUM LENTON STRANGE, a citizen of the United States, residing at Hernando, in the county of Gltrus and State of Florida, have invented certain new and useful Improvementsin Stovepipe- Clamps, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved combined stove pipe clamp and coupling and its object is to provide a device of thls kind which is very simple, efficient and practical in construction and capable of be-' ing cheaply made and sold at a reasonable profit.

Another object is .the provision of. a clamp, which is capable of being stamped and formed from a single piece of sheet metal in one operation of a die, or one operation of a drop forge method. 7

Another object is to provide a clamp in the form of a band, which is provided with free ends adapted to connect when the band is engaged about the stove pipe, and provided with upper and lower over-turned flanges or parts to be engaged by the two sections of stove pipe to be joined and clamped together, thereby preventing the downward movement of the upper section and upward of the lower section, in fact.

prevent relative movement of either section.

While the design and construction at present illustrated and set forth is deemed preferable, it is obvious that as a result of a reduction of the invention to a more practical form for commercial purposes, the invention may be susceptible to changes, and the right to these changes is claimed, provided they are comprehended within the scope of what is claimed.

The invention comprises further features and combination of parts, as will be hereinafter set forth, shown in the drawings and claimed.

In the drawings Figure 1 is a View in elevation showing the improved combined clamp and coupling as applied to adjacent stove pipe sections, showing the clamp wherein the ends are joined,

Fig. 2 is a vertical sectional view through the two stove pipe sections showing the clamp in position.

Fig. 3 is a cross sectional view on line 33 of Fig. 2 showing the'manner of counect ng the ends of theclamp,

Flg. 4 is a detail sectional view on line of Fig. 2; and

Fig. 5 is a detail perspective view of the two ends of the combined coupling and clamp.

Referring to the drawings, 1 designates the upper section of a stove pipe and 2 the lower section. In practice the upper section telescopes over the lower section, and in order to prevent relative movement of the two sections, an improved combined clamp and coupling is provided. This COIIlblIlGCl, clamp and coupling 3 is constructed from a single piece of sheet metal 1n circular outline, and the upper portion of the band is over and in-turned, thereby formlng an abutment flange 4. In fact the lower marginal portion of this abutment flange is flared as shown at 5 against which the uppermarginal edge of the lower pipe section abuts, thereby preventing movement of the lower plpe' sectlon in an upward d1rect1on.'

The lower portion of the band or clan'ip v or coupling is outwardly and upwardly turned, the fold thereof being designated by the character 6, thereby providing an abutment flange 7. The upper marginal edge of this flange is flared outwardly as shown at 8 in order to provide a shoulder against which the lower marginal edge of the upper pipe section abuts thereby preventing relative downward movement of said section.

Adjacent the ends of the combined coupllng and clamp, the ends of the inwardly, downwardly and outwardly and upwardly turned flanges terminate in lateral portions 9 and 10, which 'abut. In other words,vthe lateral portions 9 abut each other, while the lateral portions 10 likewise abut, thereby holding the band or clamp in position and eonformingto the pipe sections. 'These lateral portions also serve as additional abutment means for the marginal edges of the pipe sections, thereby additionally preventing relative movement of the pipe sections. In order to permit these lateral. portions to abut for the above purposes,

the ends of the band or clamp slightly The invention having been set forth, what is claimed as new and useful is 1. In a device as set forth, a pair of adjacent pipe sections, a combined clamp and coupling therefor comprising a band telescoping respectively within'one section and over the other sectlon, the circular marginal edges of the band having inwardly and sure prevention of relative movement of the pipe sections, the ends of the band being overlapped, and said lateral parts additionally serving to hold the band in uniformity with the pipe sections.

2. As an article of manufacture, a combined clamp and coupling comprising a sheet metal band adapted to telescope respectively within and over adjacent ends of a pair of pipe sections, the opposite marginal portions of the band having respectively inwardly and downwardly, and outwardly and upwardly disposed flanges, the marginal edges of said flanges being inwardly and outwardly turned against which the marginal edges of the pipe sections are adapted to abut to prevent relative movement thereof, the

7 ends of the band adapted to overlap, the

ends of the flanges having means which together with the overlapping ends of the band act to hold the band conforming to and engaging the pipe sections. r

s an article of manufacture, a com bined clamp and coupling comprising a sheet metal band adapted to telescope respectively within and over adjacent ends of a pair of pipe sections and provided with separable ends, the opposite marginal portions of the band having respectively inwardly and downwardly, and outwardly and upwardly annular abutment means to be engaged by the respective marginal edges of said pipe sections to prevent relative movement, the construction and arrangement of the separable ends and the ends of the abutment means being such as to act to'hold the band conforming to and engaging the'pipe sections.

4. As an article of manufacture, a combined clamp and coupling comprising a sheet metal band adapted to telescope respectively within and over the adjacent ends of a pair of pipe sections, the opposite marginal portions of the band having respectively inwardly and downwardly, and outwardly and upwardly disposed flanges, the respective marginal edges of said flanges being inwardly and outwardly turned against which the marginal edges of the pipe sections are adapted to abut to prevent relative movement of the sections, and to permit pipe sections of relatively different diameters to be united.

In testimony whereof I hereunto affix my signature.
